LIGHT REFLECTION AND REFRACTION
10
CHAPTER
Previous Years' Examination Questions
[Sample Paper, Delhi, Outside Delhi, All India, Foreign, Comptt.]



1. Where will the image be formed by a concave mirror when an object is placed between the
pole and the focus point of the mirror?                    [CBSE 2005 (D.B.)]

2. What are the values of (i) the angle of incidence, and (iz) the angle of reflection for normal
incidence on a plane mirror surface?                       [CBSE 2005 (A.I.)]

3. Where will the image be formed by a convex mirror if the object is placed between infinity
and the pole of the mirror?                                       [CBSE 2005 (F)]

4. A ray of light is incident on a convex mirror as shown.

Redraw the diagram after completing the path of the light ray after reflection from the·
mirror.                                                                       [CBSE 2006 (A.I.)]


5. Take down this figure into your answer book and complete the path of the ray.

6. Why does a ray of light bend when it travels from one medium into another? [CBSE 2009 (D.B.)]

7. Draw the given diagram in your answer book and complete it for the path of ray of light
beyond the lens.                                                  [CBSE 2009 (F), CBSE 2013]


8. The outer surface of a hollow sphere of aluminium of radius 50 cm is to be used as a
mirror. What will be the focal length of this mirror? Which type of spherical mirror will it
provide?                                                                                    [CBSE 2010 (D.B.)]

9. What is nature of the image formed by a concave mirror if the magnification produced by
the mirror is+ 4?                                                                      [CBSE 2010 (D.B.)]

10. Which phenomenon is responsible for making the path of light visible ? [CBSE 2012 (D.B.)]

11. What is the magnification of the images formed by plane mirrors and why? [CBSE 2015 (D.B.)]

12. What is meant by power of a lens? [CBSE 2015 (D.B.), 2017 (F)]
